我有一个如图所示的输入区域。由于价格至少是多少,我不知道如何为数据库匹配输入此价格。
<?php
$type = $_POST['type'];
$conn = mysqli_connect();
$query = "select type, description, price from product where type = ?";
mysqli_stmt_bind_result($pStmt, $type_r, $description_r, $price_r);
答案 0 :(得分:1)
将查询更改为(> =,因为您说价格至少是):
$query = "select type, description, price from product where type = ? and price >= ?";
并在$price
之前实例化mysqli_stmt_bind_param($pStmt,'sd', $type, $price);
:
$price = $_POST["dollar"] . '.' . $_POST["cents"];
